CHECK-ROW CORN-PLANTER.

SPECIFICATION forming part of Letters Patent No. 560,908, dated May 26, 1896.

Y Application filed August 7,1895. Serial No. 558,459. (No model.)

To @ZZ whom, it may concern:

Be it known that I, JOHN W. LINDQ UIsT, a citizen of the United States, residingat Galesburg, in the county of Knox and State of Illinois, have invented certain new and useful Improvements in 'Check-Row Corn-Planters, of which the followingis a specification.

rlhe checlrrow corn-planter to which the invention that is herein described pertains is of that general class or type of such planters in which the seed measuring and dropping in that a wheel or endless belt traction-wheel, as the case may be, in passing over ridges or higher places, stones, roots, Vor other things that will raise it, and in passing over low places and soft places which will permit it to lower, will thereby cause the Wheel to rotate in a given distance to a greater extent than when the planter is moved the same distance over a level and uniform surface, and that this intermittingly-increased rate of speed of rotation of the wheel Will cause the seeding mechanism, which the wheel directly or indirectly operates, to deposit the charges or hills ofseed at different distances apart, and thus prevent successful oheckrow planting or planting in rows transversely to the path of the planter.

The main object of my invention is to provide what may be termed a governor, which will cause the seed-dropper driving wheel or Wheels to impart uniform movements to the seeding mechanism in the passage of said wheel at either side of the planter over soil of different kinds, ridges, low places, stones, roots, and other conditions, rolling over which the rotary movement of the wheel in a given distance, in such planters as heretofore constructed, is increased 'and the speed of rotation variable and notuniform; and to the end of carrying out this main object my improvement consists in its essential or main feature in the use of a weighted pendulous rod suspended from the planter frame or axle in such manner that it may freely swingby gravity laterally of the planter, and thereby r,e

tain a vertical position when the wheel at either side of the planter in traversing the rows being planted is raised or lowered and thereby raises or lowers one side of the planter f frame or axle, from which the weighted pendulous rod is suspended, into an inclined poits angular relation to said frame or to the axle, act as a governor, as hereinafter de- V scribed, to prevent the excess of rotation of said wheel or wheels, which arises, as described, from disturbing the uniform action of the seeding mechanism in traversing the ground being planted, and thereby cause the charges of seed to be deposited at uniform distances apart, and consequently in substantiallyaccurate check-rows. This essential feature of my invention is hereinafter described and made the subjectmatter of claims hereto appended, as are also other improveinents which have been evolved in car-4 rying out the essential or main feature.

A further object of my invention is to furnish an improved marker for check row planters, which is hereinafter fully described and its novel features expressed in appended claims.

Mechanism embodying the preferred constructions and combinations of the different parts and the adjacent parts of an ordinary corlrplanter in which my improvements are incorporated is illustrated in the accompanying drawings, in which- Figure l is a top plan of part of an ordinary corn-planter with `my improvements incorporated therewith; Fig. 2, an enlarged rear elevation of the frame on which part-s of my improvement are mounted, rear elevation IOO Ass

The forward frame A, Fig. l, having transverse frame-bars a a', tongue a2, seed-boxes a5, and runners CL4, has the forward ends of the side frame-bars a5 of the rear frame A/ hinged thereto at a6. The rear frame A/ has transverse bar a7 and is supported on the axle as, which is in turn carried on the wheels a d10. The seat d. is supported on the rear frame. The sprocket-wheel B is fixed to the wheel d10 and geared by a sprocket-chain b with a sprocket-wheel b', Fig. 2, which is fixed to the boss of one member b2 of a clutch b3. The member b2 is mounted on the shaft b4 to revolve thereon while held from endwise movement thereon by a set-screw b5, the inner end of which seats loosely in a circumferential groove in said shaft. The othermember, b, of the clutch is splined on the shaft b4 to revolve therewith and slide lengthwise thereof, and has a subconical-shaped end bl, which seats in a corresponding recess in the adjacent part of the member h2. The frictionclutch described is operated by a hand-lever bs, pivoted at b9 to a plate Z210, fixed to the bar a", and has a sector-shaped end Z111, Fig. 3, with a curved slot 1912, eccentric to the center of motion b9 of the hand-lever, through which slot projects the outer end part of a stud Z913, the inner end part of which is fixed to and projects through a colla-r b1, and together with a stud 1115, which is also fixed to the collar Z314, rest in a circumferential groove 1916, Fig. 2, dot lines, in the outer end part of the member?)6 of the clutch and permit said member to revolve freely within the collar b1, while forcing it into and out of frictional contact with the member b2 by means of the lever bs in an evident manner and for the purpose of throwing the shaft b4 into and out of gear with the wheel am.

The parts described in the last preceding paragraph, except the peculiar clutch mechanism described therein, are such parts of an ordinary corn-planter as will suffice to illustrate my improvement and its connection therewith.

The shaft b is supported in bearings c', Fig. 2, dependent from a frame C, which is fixed to the bar a. A pinion c2 on the shaft b4 gears with a pinion d on a shaft d', also having bearings in arms projecting from the frame C. To the upper portion of the shaft d is lixed a cam-wheel D, or wheel having a circumferential groove in its perimeter. Diametrically opposite sides d3 of the groove d2 are in different planes and each in the plane of revolution of the cam-wheel D, while the -intermediate sides or parts are in same inclined planes to the plane of revolution of the cam-wheel and form the cams d4 di, which act, as hereinafter described, on a pin e, (shown in dot lines,) that projects laterally from one end part of a bar E. The mid-length part e2 of the bar E is of dovetail form in its cross-section, and is freely slidable endlong of itself in a similarly-shaped groove e3 across the upper end part of a lever e4, to the lower end of which lever is pivotally connected a rod e5, (see dot lines, Fig. 4,) which connects the oscillatory lever @4in an ordinary manner (not further shown) with the seed measuring and dropping valves (not shown) of an ordinary planter. The lever el is pivotally mounted on a stud -pin e, which projects from the frame C through the upper end of the lever e4 and through a slot eT in the bar E, which slot permits the bar E to slide back and forth endlong of itself in the dovetailedshaped groove in the lever e4, for purposes hereinafter described.

The means hereinbefore described constitute means for operating the seeding mechanism of a corn-planter by gear connection with the wheels or a wheel of the planter, and while embodying certain improvements, such as the peculiar clutch mechanism, the camwheel D and bar E would still be, as are all its predecessors, inefficient as a check-row planter, because the interspaces between the deposits of seed made thereby will be varied in distance by the passage of the wheel or wheels over higher or lower places, over alternating hard and mellow soil, over roots of corn, grass, or other material, and over clods or other conditions that will intermittingly increase the rotatory movements of the wheel in given distances, and I will nowproceed to describe my improvement designed to correct this defect in planters in which the seed measuring and dropping mechanism is actuated by the wheel or wheels of the planter.

The horizontal end g of the pendulous L- shaped bar g is journaled at its rear end part in a bracket g2, supported by the axle a8, and at its forward end part by a bracket g3, projecting from one of the bars a5, the object being simply to journal it to the axle or the `frame of the planter, or to both, in such manner that its pendent or pend ulous end part G, which constitutes the main feature of my invention, can and does retain a vertical posi- ICO IIO

tion when the axle is raised or lowered at either of its ends by the wheel passing respectively over high or low places, or, as may be said, the pendulous part G swings laterally of the planter when either side of the planter is raised or lowered, as stated. A weight g4 is mounted on the bar G to render its action effective and is adjustable thereon in higher or parts of the governor.

lower planes to adapt it to operate effectively under dierent conditions of the operating The forward end of the part g carries a pinion g5, which gears with a pinion g, carried on a short shaft g?, Fig. S, which shaft is journaled in a bearing g8, fixed to a bar a5. The shaft Q7 carries a crankarm gg, Fig. 9, having a slot g10,fthrough which an arm h projects, which is carried by a crankarm 7L', that projects from a cam-cylinder H,

which is journaled on an axle h2, carried by arms h3, which project laterally from the frame C.

The cam-cylinder II is also an important feature in my invention in that it has a V- shaped cam-groove h4 in its peripheral surface or cam-groove formed of two grooves h5 h5, which, starting from a common point k7, extend forwardly and diverge from each other at an. angle, as shown best at Fig. lO, which figure shows the opposite side of the cam-cylinder from that side shown at Figs. 2 and 4. The bar I is slidable lengthwise of itself on a stud-pin fi, which is fixed to the frame C and extends through a slot t" in said bar. A curved slot 712 in the forward end of the bar I receives the stud-pin e8, which projects therethrough from the adjacent end of the bar E. The walls of the curved slot i2 fit snugly to the stud-pin e8, so that back-and-forth or endwise-reciprocatin g movement of the bar I will communicate the same movement to the end wise-slidable bar E, while the bar Eis permitted to oscillate freely without oscillating the bar I by reason of the pin i moving in the slot ft2. The outer end of a stud-pin t3, carried on t-he end of the bar I, adjacent to the cam-cylinder H, extends into the cam-grooves h5 7L, as shown best at Fig. 3.

In operation in the field and while the planter-wheels are in substantially the same plane the pin 3 is at rest in its normal position in the cam-groove h4 at the point 71,7, Where the grooves h5 h6 unite, as shown at Figs. 2, 3, and 10. t At Fig. 5 I have by dot lines shown one of the wheels alo as having dropped into a low place and the inclination given the axle thereby and by which the angular relation between the axle and the pendulous rod or bar G has been changed in same way as if the pendulous bar G had been swung toward the right-hand side of the machine, thus partially rotating the rod g and its pinion g5, and thereby partially rotating the pinion g and giving a throw to its crank-arm gg, (see dot lines at Fig. 8,) which crank-arm in turn gives a throw or swing to the crank-arm h', t and thereby partially rotates the cam-cylinder I-I7 as shown by dot lines at same figure, and in such direction that the pin Q13 is made to traverse the cam-groove h5 toward the upper and forward end of said groove and thereby move or thrust the bar I toward the lever e4, which bar I in turn and at the same time moves the bar Ein the direction shown by the arrows at Figs. 2, 3, and fi, andthereby advances the pin e with reference to the wheel D in the direction of motion of theadjaceht side of said wheel or of the cam-groove d2, said cam-groove revolving in the direction indicated by arrows at Figs. l and 3. This movement of the pin e will be governed in extent by the distance the wheel uw was lowered, and hence by the increased rotary motion given the wheel in passing through said low place, and hence the movement of the pin e, as described, will delay the action of the inclined parts or cams d4 on the pin e to the same extent that the described lowering of the wheel would hasten the action of said cam-grooves d3 on the pin e without the use of the pendulous rod G and the intermediate parts gearing it with the cam-wheel D,and th us the dropping of charges of seed will be made at predetermined uniform distances apart and not be affected by the rising and falling movements of either wheel. The wheel am in raising from the low place described will bring the axle as and the pendulous rod G again into the same relative positions shown by full lines at Fig. 5 and in an evident manner give a reverse movement to the cam-cylinder H and rotate it to such an extent as to bring the pin i3 into its normal position at the point h?, and thereby give a re- It Win be evident frm nieder unes at Fig.

5 that if the left-hand wheel a9 is raised by passing over corn-roots or otherwise it will` incline the axle in same manner as lowering the right-hand wheel alo, and thereby advance the pin e and delay the action of the cams Z4` thereon in same manner as done by the described falling movement of the `wheel al". The falling movement of the wheel am and the rising movement of the wheel a9 rotate the cylinder II in same direction and cause the pin 'i3 to traverse the same cam-groove h5, and the rising movements of the wheel d10 and falling movements of the wheel a9 will incline the axle in an opposite direction, and hence partially rotate the cylinder H in an opposite direction to that hereinbefore described, and thereby cause the pin i3 to traverse the cam-groove h6 toward its forward and outer end, and thus act on the bars I and E and pin e to move them in the same direction and for the same purpose as hereinbefore described in respect to their movements given them by the cam-groove h5. When the axle is inclined lowest at its end carrying the wheel a9, as last described, in rising to its normal or horizontal position the cylinder H will be IOC IIO

given a reverse partial rotation and the pin 3 be made to traverse the cam-groove 71,6 back to its normal position at the point k7.

The inclined part CZ'L or cam part of the groove cl2 at one side of the wheel D is such that it will raise the pin e and give a throw in one direction t-o the lever e4, While the same inclined groove (Z4 at the diametrically opposite side of said wheel will force the pin e downwardly and give the lever e4 a throw in an opposite direction, thus imparting to the lever e4 the necessary oscillatory movement for operating the seed slides and valves of an ordinary planter, whether such slides be of the reciprocating, oscillating, rotary, or other type.

In start-ing at the ends of rows or bouts, the clutch b3 being first released by swinging the lever bs, the driver may by means of the crank J partially rotate the shaft CZ and wheel D in whichever direction necessary to place the inclined parts d4 of the cam-groove in position to act on the pin e to operate the seed measuring and dropping mechanism in proper time for depositing the seed, in beginning the new rows, in line with or in check-row with the last deposits of seed in the last rows completed. In any part of the rows being planted the same means maybe used to bring the inclined parts d4 of the cam-groove d2 into proper relation to the stud-pin c to effect correct check-row deposits of seed when such parts, from any cause, have been thrown out of such proper relation to each other.

The pin e passes through a hole Z in the inner end of the marker-bar L and through a slot Z in the inner end of the marker-bar L. The bars L L are parallel and are held in alinement with each other by sleeves Z2, each of which sleeves is bolted or otherwise secured to one of said bars (as shown they are bolted to bar L) and permit the other bar to slide back and forth therethrough end wise of itself. The outer ends of the marker-bars are provided, respectively, with ordinary marker-shoes Z3 Z4. A link-rod Z5 is pivotally connected at one end with the bar L a short distance from the end of said bar, and is removably connected at its other end with the lower end of the lever c4 bya bolt ZG. By removing the nut on the bolt ZG and the link-rod Z5 therefrom the marker-bars L L' may be turned over to the opposite side of the planter from that shown at Fig. G, when said link-rod and nut are replaced and the marker-bars are in position for marking when the planter is traversing the ground in an opposite direction to the direction for which adjusted, as shown at Fig. 6. The marker-bars are supported by the hooks m at proper operative heights.

At Figs. 6 and 7, in which the lever e4, as shown by full lines, has completed its throw toward the right-hand side of the machine to effect a discharge of seed, the link-rod Z5 has pushed the bar L outwardly until its outer end or shoe Z3 is in position to follow in the path of the shoe Z4 on the'bar L, until the lever c4 is swung toward the left-hand side of the machine to effect another discharge of seed, in making which movement the lever c4, through the instrumentality of the link-rod Z5, will draw the rod L and its shoe Z3 inwardly, as shown by dot lines at Fig. 6.

The straight line Z7, Fig. Il, represents the mark made by the shoe Zl of the bar L. The small circles at same ligure represent the deposits of seed, and if the planter is assumed to be moving in the direction indicated by arrow at said figure then the short oblique lines ZS represent the marks made by the shoe Z3 of the bar L as the bar L is drawn toward the planter by the throw of the lever e4 toward its dot-line position at Fig. 6. The short lines Z9 paralleling the line Z7 indicate the marks made bythe shoe Z3 of the bar L', while the lever e4 is at rest between its throws, and the oblique lines Zl0 indicate the marks made by the shoe Z3 as the bar L is thrust ontwardly by the lever e4 in making throws from its dotnline position to its full-line position. (Shown at Fig. 6.) The lines Z7, Z8, Z9, and Z10 all aid in indicating the last rows planted as to their course across the ground, and the marks Z8, Z9, and Z10 aid especially in rendering visible the places of deposit of the hills of seed and thereby the check-rows.

The advantages of my invention, both as to the governor for preventing` rising and falling movements of the wheels from affecting the uniform distances between the charges of seed and as to the marker for indicating the place of deposit-of the seeds and the line of such deposits in both directions across the field, will be apparent, and the operation will be understood from the foregoing description, it being particularly noted that while still within the purview of my invention various changes may be made in the details of construction and especially in the means for transmitting motion from the pendulous weighted rod to that part of the check-roweil mechanism on which it acts.

I am aware that pendulous rods are shown in certain patents, which rods oscillate in a plane lengthwise of the planter and operate only when one end of the planter is on higher ground than its other end, and which pendulous rods are not operated at all bythe rising and falling movements of the planter-wheels independently of each other in such manner as to elevate or lower one side of the planter, and I do not herein claim such as my invention, the most essential feature of my invention being a pendulous rod which swings laterally of the planter, and hence operates when either wheel is raised or lowered, as is constantly occurring in the operation of planting, and from which arises the defective checkrowing by planters in which the seed-dropping mechanism is actuated by the planter wheel or wheels.
